I am not sure on how far to drive it but suck some up with the brake booster vacuum line (leave end thats connected to engine connected to engine stick other end in can) then shut your engine off for 10 minutes then go drive it around. It will smoke like **** but thats just the carbon buildup getting burnt up.

Better yet, split it in thirds. Put 1/3 in the gas, 1/3 in the oil and 1/3 in the vacuum booster hose. Since it says to use 1/3 of it anyway this is the way to go. If you have put it in the booster with in the last 3,000 to 5,000 miles ( I think that is what the can says) than don't worry about it. When I put it in my crankcase I usually change the oil within a week so yeah 100 miles sounds right.
